Nucleosomal chromatin in the mature sperm of Drosophila melanogaster.. Drosophila melanogaster

Nucleosomal chromatin persists in the mature sperm of Drosophila melanogaster. Paternal epigenetic marks of repression and active transcription are found within many genes essential for embryogenesis. These marks are delivered at fertilization and are subsequently maintained in the early embryo. Overall design: The detection and localization of nucleosomal DNA in D. melanogaster spermatozoal chromatin.
